I feel that there needs to be a more wholly-inclusive word - or initialism - to cover the group. You can't just keep adding additional letters to an acronym forever, and it's becoming unwieldily as more groups require additional labelling.

I don't have a suggestion for a solution, as not being a member of said group I feel it's probably better that I leave suggesting solutions to someone else out of respect... But from a marketing and visibility perspective, we need the acronym to be more readable! :)

(Also to be less rigid when it comes to people misrepresenting the acronym... I don't think it helps when someone tries to promote something positive for the group, and then be immediately berated because of a missed detail :) )
